Remote Control Plugin doesn't work with proxy

[uilzzw]

When I turned on Remote Control Plugin, the console prompts the binding port to fail when starting.The following is the prompt message：
Loaded plugin "RemoteControl" RemoteControl using QtWebApp version 1.6.4-stellarium StaticFileController: docroot=/usr/share/stellarium/webroot, encoding=UTF-8, maxAge=60 StaticFileController: cache timeout=60000, size=1048576 RemoteControl enabled HttpListener: Cannot bind on port 10109: Operation on socket is not supported Loaded plugin "RemoteSync" stel.plugin.remoteSync: Plugin initialized

You have someone service on this port already

I have no service running on this port.I tried other ports. The prompt is the same error.

Is it caused by my use of ordinary users?

I started trying it with root user just now. Can run normally

My user is in the root group, I don't know what caused it.

I see no problem in my linux with common user

I figure out what the reason for this problem is. The reason is that I have opened a global proxy. There is this line in the log.
Using HTTP proxy: "" "" "127.0.0.1" "8118"
But I haven't figured out yet what causes it to get two null values.

If you mean the two "" items, they are proxy user and proxy password. See StelApp::setupNetworkProxy():

qDebug() << "Using HTTP proxy:" << proxyUser << ppDisp << proxyHost << proxyPort;

If you mean the two "" items, they are proxy user and proxy password. See StelApp::setupNetworkProxy():如果您指的是这两个 "" 项目，它们是代理用户和代理密码。请参见 StelApp::setupNetworkProxy() ：

qDebug() << "Using HTTP proxy:" << proxyUser << ppDisp << proxyHost << proxyPort;

I am very curious why after opening a global proxy, opening the remote control plugin will fail. I read a little remote control plugin code and didn't look carefully. Isn't the http service of this remote control plugin run independently?

You can see the call to QNetworkProxy::setApplicationProxy in this function, so this is an app-global setting that will affect all HTTP connections (and servers, I suppose).

But I don't really know this code, so you'll have to study it more thoroughly to understand what's going on.
